Abstract

This study aims to obtain a good concentration of IBA and plantain and is suitable for root induction in Dendrobium sp. The benefit of this study is to provide information about the successful root induction of orchid plantlets Dendrobium sp. In vitro culture and creating formulations using IBA hormones and organic plantain ingredients in in vitro culture media optimally. This research has been carried out at the YAHDI Plant Tissue Culture Laboratory. Rooting orchids Dendrobium sp. In vitro using MS basic media which was added with IBA (Indole 3 Butyric Acid) 0 ppm, 2 ppm, 4 ppm, and 6 ppm, and added with plantain pulp with levels of 0 g/l, 100 g/l. and 200 g/l. This study was a factorial experiment with 2 factors compiled based on a 4 x 3 Complete Random Design (RAL) with 12 treatment combinations. The data obtained was analyzed for variance analysis (ANOVA). If there are results that have a real effect, it is followed by the DMRT (Duncan Multiple Range Test) test at the level of 5%. (1) The results of the study showed that the treatment of the variables of the number of roots, plant height, and root length was influenced by IBA. (2) The treatment of the variables of the number of buds, the number of leaves, the number of roots, the height of the plant, and the length of the roots is influenced by plantains. (3) The treatment of the variables on the number of roots, root length, and leaf width were influenced by the interaction of IBA and banana pulp.

Abstract

This study aims to determine the validity and reliability of interactive multimedia with Adobe Animate CC on food digestion material. The research method used is Research and Development (R&D), with a 3-D development model, which includes defining, designing, and developing. The research instrument used was a validation sheet with aspects of assessing the feasibility of material content, linguistic aspects, presentation aspects and aspects of interactive multimedia characteristics. Validation was carried out by 5 validators selected by purposive sampling by considering that the validator is an expert in the field of education and media, especially technology-based media. Media assessment is done qualitatively through a checklist assessment which is then converted into a quantitative value with Likert scale provisions. The validation data obtained from the validator's assessment was then analyzed using the Aiken validation analysis technique and its reliability was measured using the intra-class correlation coefficient. The validation results showed that the interactive multimedia was declared valid with an average validation score of 0.93 with 5 Likert scales. The reliability test results with the SPSS Statistic program obtained a value of 0.788 which shows excellent reliability. Thus, it can be concluded that this interactive multimedia is valid and suitable for use in learning.

Abstract

Leaflets are learning media in the form of printed media that provide a summary of learning material to be memorized by students. Leaflet media allows students to learn at their own pace. This study aims to produce products and analyze the feasibility of leaflet media for bacterial diversity in fibric peatlands on the sub-matter of Indonesian biodiversity. The research method used quantitative descriptive method with Content Validity Ratio (CVR) and Content Validity Index (CVI) analysis. Data collection was carried out through leaflet media validation by 3 high school biology teachers and 2 biology education lecturers who assessed the suitability of the research instrument items. The results showed that the leaflet of bacterial diversity in fibric peat soil on the submaterial of Indonesian biodiversity obtained a Content Validity Ratio (CVR) value of 1, indicating high validity, and a Content Validity Index (CVI) value of 1, indicating excellent quality. This means that this leaflet is valid and very feasible to use as learning media in high school in the material of Indonesian biodiversity.

Abstract

This study aims to determine the levels of blood plasma protein in pregnant white rats (Rattus nervagicus) that consume Organic MSG and Synthetic MSG. This research method is experimental using a Completely Randomized Design (CRD) by random sampling 21 pregnant white rats with 3 replications and 7 treatments consisting of positive control treatments, P1 = 0.5 ml Organic MSG, P2 = 1 ml Organic MSG, P3 = 2 ml Organic MSG, P4 = 0.5 ml Synthetic MSG, P5 = 1 ml Synthetic MSG, P6 = 2 ml Synthetic MSG for 19 days. The variables measured were blood plasma protein levels measured using a refractometer with units of g / dL. The data tested using SPSS analysis with one way ANNOVA test then continued with Duncan's Multiple Range Test (DMRT). The results showed that Organic MSG had a positive effect on blood plasma protein levels which were significant to the difference in blood plasma protein levels. This can be implied in the health of pregnant rats if there is MSG that enters it will provide viscosity to the blood so that blood plasma protein will be high working hard to produce white blood cells to balance red blood cells that affect immunity. The blood plasma protein levels of pregnant white rats given liquid Organic MSG were the highest at 13.562 g/dL and the lowest at 13.55 g/dL.

Abstract

This study aims to identify potential antimalarial compounds targeting the Plasmodium falciparum lactate dehydrogenase enzyme (PfLDH), given the parasite's dependency on glycolysis for energy production. Considering the high similarity of LDH enzymes across Plasmodium species, developing novel PfLDH inhibitors may offer therapeutic benefits, particularly against P. vivax, P. malariae, and P. ovale. Computational approaches were employed to screen natural compounds from the Cratoxylum genus (Cratoxylum glaucum and Cratoxylum arborescens). Molecular docking was performed using Molegro Virtual Docking (MVD) to assess binding affinity. SwissADME was utilized to evaluate pharmacokinetic, physicochemical, synthetic accessibility properties, and ProTox II was used for toxicity prediction. Molecular docking results indicated that fuscaxanthone C and 3-geranyloxy-6-methyl-1,8-dihydroxyanthraquinone exhibited strong inhibitory activity against PfLDH, with rerank scores of -103.068 kcal/mol and -111.141 kcal/mol, respectively surpassing the reference ligand chloroquine (-94.307 kcal/mol). Pharmacokinetic analysis revealed that all compounds, except stigmasterol and fuscaxanthone C, met Lipinski’s Rule of Five. Toxicity prediction categorized fuscaxanthone C as Class III (toxic). Additionally, synthetic accessibility predictions indicated that all compounds, except stigmasterol, are easy to synthesize. Natural compounds from the Cratoxylum genus, particularly 3-geranyloxy-6-methyl-1,8-dihydroxyanthraquinone, show promise as PfLDH inhibitors. Despite its potency, fuscaxanthone C's toxicity profile warrants caution. Further studies are needed to validate these findings through in vitro and in vivo testing.

Abstract

Skin dehydration is a common issue affecting 40–50% of the adult population, resulting in dry, rough, and dull skin, as well as itching, irritation, and premature aging. The "back to nature" trend has increased interest in natural skincare products that are more environmentally friendly and gentler on the skin. Virgin coconut oil (VCO) is a popular natural ingredient known for its ability to maintain skin moisture and provide protection. This study aims to develop a liquid soap formulation using VCO to address skin dehydration. The research methods included formulation and evaluation of liquid soap through organoleptic testing, foam stability, specific gravity, pH, as well as hedonic and irritation tests. The results showed that: (1) Formula III met all physical evaluation parameters, including organoleptic characteristics, foam stability and height, specific gravity, and pH, in accordance with SNI standards; (2) Formula III was the most preferred by panelists in the hedonic test and caused no skin irritation based on irritation test results. Therefore, Formula III can be concluded as the optimal formulation for VCO-based liquid bath soap.
